MST Expressor

The MST Expressor allows you to use expression pedals with your modular, taking a “hands-off” approach to expand your control and creativity. It has two identical powered expression pedal processing units in one handy module, allowing you to do things such as:

Control volume with your foot

Attenuate CV or audio if no expression pedal is plugged in

Add positive or negative voltage with the flick of an ankle:

Sweep a filter cutoff

Transpose CV

Pitch bend

Direct audio volume control

Attenuate and expand external CV

LFO rate adjustment

Modulation amount control

And more…

Features:

Processes audio and DC signals

Two discreet expression pedal input channels (1/4″ TRS jacks)

External signal (audio or CV) input per channel

Precise output adjustment: attenuator/scale control per channel

3-position switch select of +5V, -5V or 0V (mute) per channel

External input bypasses the switch voltage (the switch voltage and external input are not active at the same time, i.e. the voltage will not offset your input signal.)
